The Singing Estate: What Happened Next (Five) surveyed what has happened to the choir which Ivor Setterfield formed in Blackbird Leys a year ago to perform at the Albert Hall. The choir is still active, albeit under a new conductor, and the programme showed how the choir has given some of its members new confidence and even helped them combat depression and Parkinson's Disease. We watched as Ivor assembled volunteers to sing the Hallelujah Chorus at Oxford Town Hall in an event called Oxford Sings. He was well satisfied with the results, saying: "I looked at the faces and there was happiness everywhere."

The programme gave a rosy picture of the choir's effects - possibly too rosy, as there seemed to be no downside at all. When the choir sang at Buckingham Palace before Christmas, it didn't contain all the original 40 members, so one wonders if everybody's experience of the choir was equally positive. Nevertheless, the programme was decorated with irrelevant but beautiful scenes of our city - just like Morse or Lewis. And it was inspiring. Prof Paul Robertson (formerly leader of the Medici Quartet) stressed how music can promote well-being, self-esteem and even good health.

Hilary Davan Wetton confesses to "having an evangelical streak", wanting everyone to experience music. In Play It Again (BBC1), he had the daunting task of teaching Jo Brand to play the organ in four months. It was quite interesting to see her struggling to learn - and eventually playing Bach's best-known organ piece at the Albert Hall (admittedly not very well). The commentator irritatingly reminded us continually of the magnitude of the task, but the programme started a useful series which encourages people to get involved in music-making.

If it was difficult turning Jo Brand into an organist, it seems equally hard to revive Samantha Mumba's career, as we saw in Get Your Act Together with Harvey Goldsmith (Channel 4). A few years ago, Samantha had six hit singles and appeared in several films but she was dropped by her record label and the film offers dried up. Impresario Harvey Goldsmith undertook to revive her fortunes but one could understand why her career was in the doldrums, as she was like a spoilt child - repeatedly turning up late for meetings and failing to commit herself wholeheartedly to the resumption of her singing career. Harvey funded a concert for her in Dublin but it was cancelled when only 24 tickets were sold for a 1400-seater venue. Eventually he arranged for her to appear at a showcase before record company executives and this may revive her fortunes, even if she doesn't appear to deserve it.

There are plenty of such 'challenge' series on TV and one of the best - The Apprentice (BBC1) - returned this week. The rationale of the series - 16 people competing for a job with Sir Alan Sugar - seems more and more implausible. Who in their right mind would want to work for such a grumpy boss? Yet it is still compulsive viewing. One pleasure is seeing the contestants' pretensions undermined by their performances. The first episode sent them to sell coffee in the street, but one team bought the wrong sort of coffee for espresso machines.

Andrew Davies has a reputation for adapting classic novels to make them 'relevant for today', which usually means that they are modernised out of recognition. So it was a pleasant surprise to see that his version of Northanger Abbey (ITV1) maintained the right period feel. The characters behaved with appropriate decorum and the heroine Catherine, as played by Felicity Jones, had the correct demeanour and didn't look as modern as Billie Piper did in last week's Mansfield Park. The parody of gothic novels was well portrayed through Catherine's dreams and imaginings, and nice touches of irony were supplied by Desmond Barrit as Mr Allen. The only jarring modernisation by Andrew Davies that I noticed was his inserting 'and baseball' after 'cricket' in Jane Austen's statement that Catherine preferred cricket to dolls.
